I've noticed that Hadoop MapReduce 1.0.4 was released in 12 October 2012,and Hadoop 0.23.4 was released in 15 October 2012. I thought that withHadoop 1.0, the Hadoop 0.2X had become discontinued. If I want to start touse Hadoop MapReduce, which version should I use?What's the difference between Hadoop MapReduce 0.2X and Hadoop MapReduce1.0?-- Best regards,

0.23.* is the last of 0.2X line. 0.23.* is used mostly by Yahoo! to stabilize the last code minus some features present in 2.x like some HDFS HA work, PB use in RPC layer etc.

Thanks,+Vinod
